In case you’ve missed it, Google engineer Benson Leung has been spending the past several months reviewing dozens of USB C cables and attempting to educate users on how USB C works and the dangers in using certain cables and other methods. Type C of course supports fast charging, as seen on devices like the Nexus 6P and Lumia 950, but one thing it doesn’t support is Qualcomm Quick Charge 2.0. This is because official Type C spec forbids the method in which QC 2.0 works. That said, we all though the newer Quick Charge 3.0 would be different, but yeah, no.

So why isn’t it up to spec? Here’s the basics. Type C spec forbids proprietary charging methods which change Vbus above 5V. QC 3.0 on the other hand can charge at up to 9V or even 12V to attain those faster charging speeds, shattering the limit.

So while Quick Charge 3.0 is technically fine, if it appears on a device with USB C it is not, and this is where things really stink. Both the new HTC 10 and the LG G5 both use both Type C and QC 3.0.

Leung has not yet confirmed what the risks are for these devices if you do opt to use their included chargers, but it’s probably not a bad idea to switch to another charging option until this whole mess clears up (and no, the LG G5 doesn’t have the option of fast charging with the same standard as the Nexus 6P).
